Welcome to ANTH 6413!

this is the only pie chart you will see all semester.

Course Goals

  • Gain the statistical knowledge to critically evaluate the use of statistics in the literature of bioanthro and related fields.
  • Get hands-on experience implementing analyses with real world data
  • Learn practical tools for doing "data-science"

All fields are becoming more data intensive

"Data-science"

Data science is an industry buzzword and cliche

From wikipedia:

"Data science is an interdisciplinary field about processes and systems to extract knowledge or insights from data.

  • In private industry, you extract insight from data to make business decisions.
  • It is also a big part of what scientists do!
  • Processes and systems for getting insight from data are important!

Data science pipeline

Confession: I believe tools matter, a lot

  • We will spend a lot of time on the "how"
  • You will become very familiar with the nuts-and-bolts of analyzing data
  • Most of your grade comes from practical exercises
  • I dont expect you to be a statistician (I sure as hell am not). But I do expect you to learn how to extract insights from data

Outcome of the course

When you leave this course, I hope you are empowered to:

  • collect your data in a format that makes your future life easier
  • explore patterns in your data visually and statistically
  • test meaningful hypotheses using appropriate statistical tools
  • communicate these results effectively using graphs and prose

Tools of the Trade

  • MS Excel
  • Commercial Statistics Packages (e.g., SPSS)
  • R – open source and free package for statistical analysis

Tools of the Trade

  • R – open source and free package for statistical analysis

Why do I use R?

  • Ignorance - Because I don’t know how to use anything else
  • Comprehensiveness – Learn this one tool well, and you can do (almost) ANYTHING
  • Reproducibility – an R script is a detailed record of exactly what I did, from the raw data file, through data transformation, to analysis and results.
  • Popularity - R is insanely popular in academia and in industry ("why hello there, marketable skills!")

What is R?

R is an open-source language and environment for statistical computing and graphics.

open-source means that anyone can look at the code to see how it works.

What is R?

One of the top 10 most widely used programming languages in the world in 2018.

What is R?

A rapidly growing system of user contributed packages.
